The Army of Western Louisiana was a part of the Confederate States Army during the American Civil War. It fought in all the major engagements during Union Maj. Gen. Nathaniel P. Banks' campaign to capture Port Hudson, Louisiana. For much of its existence, it served under Maj. Gen. Richard Taylor. Perhaps its crowning achievement was its victory in April 1864 at the Battle of Mansfield. On June 17, 1864, Maj. Gen. John G. Walker was ordered to relieve General Taylor of command of the Army of Western Louisiana, as Taylor had been promoted to lieutenant general and sent to the larger Army of Tennessee. In September and October 1864, the infantry of the Army of Western Louisiana campaigned in southern Arkansas. The army surrendered along with all the troops of the Trans-Mississippi Theater on May 26, 1865.
